Light control ** 1. Lighting Challenge: The lighting in the conference venue is usually uncontrollable. When there is insufficient light, you can use an external flash or a reflective board to fill in the light, but you must pay attention to avoid overexposed or strong shadows. 2. Shooting format: If the lighting is complicated, it is recommended to use the RAW format (for photography) so that there is more room for adjustment in the later stages. ** 5.

Close-up: - Close-up shots, whether from a close distance or a long distance, had to be taken care of, such as shooting a leader's speech. - When shooting at close range, if you use a flash, you should raise it to shine on the ceiling and fill the character's light with reflected light to avoid the face being too bright. - For cameras with red-eye reduction function, turn on this setting. - When shooting with a long focus, the flash can be directly aimed at the object in front of the camera. The camera is advanced and the image sensor has high resolution. When the light is good, there is no need to turn on the flash. The CPU can be adjusted appropriately (such as 400 - 800). - When the flash could not be turned on and the camera equipment was not good, a tripod could be used to slow down the shutter to get a clear photo. 2. Meeting location: - Choose a position where you can see the entire scene, so that the theme of the meeting and the characters can be integrated into the camera, and you can use the wide-angle lens to shoot a panoramic view. - When shooting a panoramic view, the light measurement should be measured from the middle and both sides. It is not recommended to use a flash. Otherwise, the face near is too white and the exposure is insufficient. You can use a tripod to extend the exposure time. 3. Dynamic photo shooting (such as award ceremony, handshake): - Flash must be used to increase the shutter speed and correct exposure to clearly fix the moving picture. - When shooting with a flash at close range, it was similar to the method of shooting leaders. If there was light, try not to use the flash. You could use a tripod to fix the shot. If there was no tripod, you could use a table, a pillar, and so on. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The reason why the DSLR overheated when recording videos was probably because the main function of the DSLR camera was photography, and recording was only an additional function. Its small size usually did not have a special cooling device. When recording, especially long-term recording, the image sensor would generate a lot of heat when working for a long time, which could easily cause the machine to heat up or even overheat. In order to prevent the DSLR from overheating when recording videos, the following measures could be taken: First, use an umbrella to block the machine from being exposed to the sun for a long time; Second, put ice water close to the machine to help cool down; Third, use multi-camera shooting. For example, when using Canon DSLR to shoot, press the stop button every 20 minutes, or press the stop button in unimportant parts. This would ensure that the files were stored normally and prevent the machine from overheating. Fourth, the camera positions could cooperate with each other to make up for accidents in time to avoid the machine from overheating due to irregular shooting. Fifth, try to shoot in the shadows to prevent the machine from entering a thermal protection state due to the sun. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
